1. Never treat colleagues as friends. Colleagues are colleagues, there is only work contact. In the workplace, colleagues are in a competitive relationship with each other. Never treat your colleagues as friends and show your heart and soul to your colleagues. Otherwise, the consequences may be serious and make you heartbroken. 2. Keep an appropriate distance from all colleagues and do not be too nice to any one colleague. Colleagues are less friendly than water, so you should maintain a polite distance from every colleague, and don't be very nice to a certain colleague for a long time. Otherwise, if one day you treat that colleague a little bit badly, that colleague will feel uncomfortable, and other people will gossip and make various speculations. 3. Stay away from people who speak ill of others behind their backs, and do not talk about another colleague with your colleagues behind their backs. Those who talk about right and wrong are right and wrong. It’s not difficult to understand why. 4. The topic of chatting with colleagues is limited to the company and work, and your own privacy must not be involved. Don’t inquire about your colleagues’ privacy, and definitely don’t expose your own.

5. Don’t be the first to be the scapegoat. 6. Demonstrate your work ability to the maximum extent. 7. Never complain about the company or the leader in front of colleagues. 8. Always maintain a high-spirited mental state, never be decadent, and never let your colleagues think you are just messing around. 9. If it is not your own job, never take the initiative to do it. First, strive to be perfect in your own job. If a colleague asks for leave or messes up something, don't take the initiative to take over. If you take the initiative to do things within the scope of other people's work, it will appear to others that they are incompetent. No one will be grateful to you, but they will have a lot of resentment towards you! Therefore, unless forced by the leader, do not do anything other than your own job. 10. If there is an opportunity for a salary increase or promotion, you must strive for it. 11. You must be sharp in life and never be a good person. 12. The boss is the boss, and the superior is the superior. Don’t take the leader’s kind words seriously. 13. If possible, try to make yourself irreplaceable. Only when your colleagues cannot replace you can you become calm and relaxed in the workplace.
